Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil.. Raw vegetable oil, obtained from seeds by pressing, solvent extraction, contains free fatty acids and other components such as phospholipids, waxes, peroxides, aldehydes, and ketones, which contribute to undesirable flavor, odor, and appearance; [1] for these reasons, all the oil has ...
Winterization of oil is a process that uses a solvent and cold temperatures to separate lipids and other desired oil compounds from waxes.Winterization is a type of fractionation (also known as fractionate crystallization), the general process of separating the triglycerides found in fats and oils, using the difference in their melting points, solubility, and volatility.
Cavitation has been applied to vegetable oil degumming and refining since 2011 and is considered a proven and standard technology in this application. The implementation of hydrodynamic cavitation in the degumming and refining process allows for a significant reduction in process aid, such as chemicals, water and bleaching clay, use.
Vegetable oil refining may refer to: Fat hydrogenation, combining vegetable oil with hydrogen to make it more saturated; Edible oil refining, process to refin a raw oil to produce an edible oil, which differ from Olive oil production. Biodiesel production by transesterification; Production of hydrotreated vegetable oil, a biofuel
Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking or hydrogenation of vegetable oil. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock.
The block scheme of the refining process is very useful to understand how the steps occur one after another in the procedure and where waste and side-products are produced. The key references are reported. I suggest to add the cross-reference to “Vegetable Oil” and to “Winterization of oil”.
Tropical oils (palm oil, palm kernel oil, coconut oil) are naturally rich in saturated fat. They can be further fractionated to increase the concentration of desired fatty acids. [2] Interesterification can be used to mix multiple types of fats, obtaining an oil with intermediate properties. For example, soybean oil and fully-hydrogenated ...
Equation (i) means that the total amount of vapour generated must be equal to the decrease in the total amount of liquid. Similarly, equation (ii) means that loss in the number of moles of A from the still because of vaporization is the same as the amount of A in the small amount of vapour generated.
